IMPROVEMENT IN LAM PBUPeNERS.

Specification forming part of Letters Patent N0. 38,926, dated June 16, 1863.

To all whom it may concern.-

Be it known that I, P. J. CLARK, of West Meriden, in the county of New Haven and State of Connecticut, have invented a new and Improved Lamp-Burner and I do hereby declare that the following is a full, clear, and exact description 3 of the same, reference being had to the accompanying drawings, making a part of this specification, in which Figure l is a vertical central section of my invention applied to the lamp of a lantern, w m, Fig. 2, indicating the plane of section; Fig. 2, a horizontal section of the same, taken in the line 3/ y, Fig.1; Figs. 3 and 4., side views of the same; Fig. 5, an enlarged detached plan of the wick-tubes.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to an improved lamp-burner of that class designed for burning coal-oil without the aid of a draft-chimney, and is more especially designed for the lamps of lanterns, although it may be advan-v tageously used for ordinary hand lamps.

The invention consists in the employment or use of two wick-tubes, having an inclined position toward each other and closed at their sides, so that a draft-chamber will be formed between them, the wick-tubes being of curved form in their horizontal section, and all arranged as hereinafter shown, so that a steady and persistent flame may be obtained, one that will admit of the lamp, when fitted in a lantern, being swung laterally or upward and downward without being extinguished.

To enable those skilled in the art to fully understand and construct my invention, 1 will proceed to describe it.

A represents a lantern, which may be constructed in the usual or any proper way, and therefore does not require a minute description.

B represents the lamp of the lantern, and C the burner, which is constructed as follows: The lower part of the burner is composed of a cylindrical box, a, on the exterior of the lower part of which a screw is cut to screw into a socket. b, in the top of the lamp. The upper part of this box a is perforated with holes 0 for the admissionof air. The

burner is provided with two wick-tubes, d, the lower ends of which pass through the box a, so that the wicks 6 may pass down into the lamp B. (See Fig. 1.) of curved form in their transverse section, as shown in Fig. 2, and they have an inclined position, gradually approaching each other from their lower toward their upper ends, as shown in Fig. 1. edges or narrow sides have plates f attached to them, so as to inclose the space g between them, said plates f extending down to the top of the box a, but not quite up to the tops of the outer sides of the wick-tubes. (See Figs. 1 and 3.) The inner sides, 1, of the wicktubes are flush with the top of the plates ff, the outer sides, 2, projecting a short distance above them, as shown in Figs. 1 and 3. Each wick-tube is provided with a serrated wheel, is, for raising and lowering the wick. These may be arranged in the usual way, and therefore do not require a special description. The wick-tubes d d, in consequence of being curved, admit of the edges or sides of the wicks being in contact with each other, as will be understood by referring to Fig. 5. The air which supplies the flame passes through the holes a in the box a and up through the space 9 into the center of the flame, as indicated by the red arrows in Fig. 1. The sides of the two flames unite or are brought in contact with each other, owing to the curved form of the wick-tubes, and hence no air can pass laterally into the flame above the wick-tubes, but can only impinge against its exterior surface. In consequence of having the outer sides, 2, of the wick-tubes extending a trifle above theirinner sides, 1, the flame is rendered persistent, or not liable to be extinguished by swinging the lamp laterally, while the central air-passage, g, prevents the flame being extinguished by an up-and-down movement.

I am aware that two wick-tubes, inclined as shown in my invention, have been used; but they have not been curved horizontally in order that the two flames may unite at their sides or edges and form a single solid flame; nor have the wick-tubes been provided with outer sides higher than their inner sides, in order to protect the base of the flame; hence the two- The wick-tubes are The wick-tubes at their wick-tube burners hitherto used will not operate as those constructed and arranged according to my invention.

1 do not claim, broadly, the employment or use, in a lamp-burner, of two Wick-tubes; but I do claim as new and desire to secure by Letters Patent- The twoinclined wick-tubes d d, when closed by plates fat their edges or narrow sides, to form a draft-space, g, and provided with elevated outer sides, 2, and inner sides, 1, on a
